A Loudoun County school social worker who was charged last week with taking indecent liberties with a minor met his alleged victim while working at the county's juvenile detention facility, according to court documents.

Franklin Todd England, 38, of Leesburg was arrested Thursday and charged with two counts of the crime, which is a felony. A spokesman for the school system said England was hired Aug. 20 as one of 19 social workers who travel from school to school conducting group counseling sessions.

In 2001, he was employed full time as a substance abuse adviser for the county's mental health department and part time as a counselor at the juvenile jail, according to an affidavit for a search warrant filed in Loudoun County Circuit Court by sheriff's investigator Dave Canham.

Canham wrote that England met the juvenile while the teenager was incarcerated in Loudoun. The teen has since been transferred to the Hanover, Va., Juvenile Correctional Center, where, the affidavit said, a letter referring to sex acts and addressed to the juvenile was intercepted in July. The alleged victim and another juvenile -- who was also incarcerated in Loudoun in 2001 -- were interviewed earlier this month, Canham wrote, and both agreed that they have exchanged letters and phone calls with England from their detention centers.

Both charges stem, however, from contact with just one of two juveniles, a boy who was 13 in 2001, said Sheriff's Office spokesman Kraig Troxell.

Sheriff Stephen O. Simpson stressed that the investigation into England's actions remained "very active."

"Having been around the county for a number of years, in a situation where he was involved with so many different groups and schools and juveniles, you never know what has gone on out there. The possibility is that there could be other people involved," he said.

Simpson urged anyone with information about England to come forward and talk with investigators.

Sheriff's investigators have seized a computer from England's Leesburg home, along with videotapes, photo albums with images of naked men, letters and a sex toy, among other items, according to court documents.

According to county human resources files, from March 2002 to January 2003, England also served a "temporary residential counselor" at one Loudoun's supervised living facilities, said county spokesman Jim Barnes.

Barnes said that the facilities, which include group homes, supervised apartments and private residences, house mostly adults but several children as well. Barnes said he did not know and could not say where England worked. His primary employment as a county substance abuse prevention specialist ended in September, before he went to work for the school system, Barnes said.

Schools spokesman Wayde B. Byard said England was placed on administrative leave with pay Wednesday, immediately after school officials were notified he was under investigation. Byard said the school system conducted customary background checks for England before hiring him, including through the FBI, Virginia State Police and child protective services. He said all came up clean.

Byard said England would not have worked with students individually, only in group settings where students discussed anger management and substance abuse issues. He said England spent some time in five county schools: Sugarland and Rolling Ridge elementary schools, Seneca Ridge Middle School, Park View High School and the county's alternative Douglass School.

Byard said that school officials were sifting through their records and that starting tomorrow would contact parents individually if England ever worked with their children.

"We are talking at every school and making sure everyone he came into contact with is notified," he said.

England was released from jail Thursday on $5,000 bond and arraigned Friday.
